a function of the form f(x) = ab' is modified so that the b value remains the same but the a value is increased by 2. how do
the domain and range of the new function compare to the domain and range of the original function? check all that apply.
the range stays the same.
the range becomes y> 2.
the domain stays the same.
the domain becomes x > 2.
the range becomes y 2 2.
the domain becomes x2

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 2

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
